The machine-readable entrance

Start from a single catalog file and you reach every dataset and every file. The schema, the file formats, and the API endpoints are gathered here.

Entry point

One catalog file

Every access starts at the catalog. Each dataset carries its id, version, status, license, path, record counts, and file list; each file carries its byte size and sha256.
